Thermostat displays P030 and motion/occupancy detection does not work; GLAS does not switch between occupied and unoccupied modes.

Safety: No high‑voltage work is needed.

• Step 1 – Clean sensor area: Wipe the front of the thermostat gently with a dry microfiber cloth to remove dust or smudges that may block the sensor.
• Step 2 – Check settings: In GLAS settings, verify that occupancy detection and any related energy‑saving modes are enabled.
• Step 3 – Test motion detection: Stand directly in front of the thermostat and move your hand slowly within 1–3 feet to see if the display wakes or status changes.
• Step 4 – Reboot and update: Power cycle the thermostat and install any available firmware updates.
• Step 5 – Replace thermostat: If P030 remains and occupancy features never respond, the internal occupancy sensor has failed. Replace the GLAS thermostat.
